Inability to access FTP sites

[Karl Strausser]

Hello,

Small network. 4 x XP SP2 PCs which used to be connected to a Small
Business Server 2000 server which had Microsoft's ISA firewall
running.

The server was replaced by a Small Business 2003 Server.

Nothing has changed on the PCs other than taking them out of the 2000
domain and connecting them to the new domain.

Since then users cannot access any FTP sites and cannot therefore
update their own website using FTP programs. There is a block
somewhere, which is instant, and we cannot locate where it is. The
2003 Small Business Server firewall is NOT running, the PCs access
the Internet through the server. The network is protected via a
firewall router, the same one which was there when the old server was
in place - nothing was changed on the firewall router.

Any ideas ?

You need to examine your firewall router. If you cannot immediately
see the cause of the problem, borrow a router from somewhere else,
reset it and configure it so that you get a connection through it rather
than through your current router. If FTP works on the borrowed router
then you know where the problem lies.

Sometimes stopping the "application layer gateway" service in the services
management console will resolve FTP issues.
